He has studied/has been studying English for an hour.

[Alice Chu]

We can use present perfect continuous to mean an action lasts for a short period of time without a break until the present, and the action is usually temporary. The verbs “live, work, teach and study” can also be used with present perfect to mean an action lasts for a short period of time without a break until the present. Please tell me if my understanding is correct.

1) Sam is studying English now. He has studied/has been studying English for an hour.
2) Lily is having dinner now. She has been having dinner for over an hour.
We don’t use “has had” here.

I don't think it's correct, no, although admittedly I don't properly see how you're understanding this.

I can't see what sentence 1 is trying to do. In what way do you think the verb study differs from other verbs? Why have you given both continuous and non-continuous forms? I can only imagine that you meant to use the present perfect continuous in both example sentences.

To indicate a short duration of an action happening right now, we usually use present perfect continuous, not present perfect.
The verbs “live, work, study and teach” can be used with present perfect to indicate a short duration of an action happening right now, but other verbs can’t.
The following sentences are correct.
1. Joe is working. He has worked for two hours.
2. Joe is teaching. He has taught for twenty minutes.
3. Amy is living here. She has lived her for a few hours.
4. Lily is studying math. She has studied it for an hour.

The following sentences are not natural.
1. Lisa is cleaning the kitchen. She has cleaned it for two hours.
2. Tom is swimming. He has swum for ten minutes.
3. Jack is playing baseball. He has played it for an hour.

Well, I don't agree with what you've said in post #3. Where did you get that information?

All the sentences are unnatural.

Here is the information I got from the Internet.
Although the above use of Present Perfect is normally limited to Non-Continuous Verbs and non-continuous uses of Mixed Verbs, the words "live," "work," "teach," and "study" are sometimes used in this way even though they are NOT Non-Continuous Verbs.

We have discussed this before. I just want to make sure if present perfect cannot indicate a short duration of an action happening right now
